70 MHz
just made my first contacts on the 4 meter band (70 MHz) using FT8.
I had an antenna i bought severals years ago in my cellar and i put it up the last couble of days. I tested it this afternoon and found out the SWR was not good at all. But using my 6 meter Yagi instead the SWR was quite good. So i had i couble of QSO´s to south western Europe using the 6 meter antenna.
In the meantime i also found out what was wrong on the 4 meter Antenna: a cold soldering connection in the antenna matching.
